Upon defining R = kll(k-1 k,,, and

Also, there would be two rates dCldt: (dCldt),= k,.R.A and

imation (B 0) leads to k,, and a second (kl 0) makes k., identical with k,,. Since these approximations are consistent with the steady state condition, I see no reason to "disallow" Both novice and expert might be confused or puzzled by a multiplicity . . of published expressions for one steady state rate constant. The purpose of my paper was t o alert readers to an apparent problem and provide its resolution. S. I. Mlller
